Review of garbage disposals fully made of stainless steel

Most garbage disposals have stainless steel grinding components but most do not have a stainless steel grinding chamber. The grinding chambers of most disposals are either high-quality plastic or galvanized steel. But are there any garbage disposals fully made of Stainless steel? Ya, there are, and they are pretty expensive too.

Stainless steel garbage disposals are very resistant to corrosion and hence they are durable. But they are also costly. So those disposals which are made of stainless steel are usually the top end models, and so far only the Evolution series by InSinkErator have them.

So here is the list of stainless steel garbage disposals;

1. InSinkErator Evolution Excel

Evolution Excel is an excellent garbage disposal that’s crammed with all the features you can find. It has a 3-stage grinding system, built completely with stainless steel, have 1 HP power and runs at 1725 RPM. It is ultra-quiet; it is the quietest garbage disposal. It also comes with features like Jam sensor circuit, Auto-reverse grind system etc.

2. InSinkErator Evolution Septic Assist

This is a ¾ HP disposal which automatically releases a bio-degrader enzyme when in use. This technology called Bio-Charge helps to break-down food wastes and control odours. The Septic Assist disposal a 2-stage grinding system and has good noise insulation while not as good as the Excel model.

3. InSinkErator Evolution Essential

This is another top end model which sports lots of premium features like 2-stage multi-grind system (same as the septic assist model) and Sound seal technology for a quieter operation. The stainless steel build gives it a longer lifetime. Unlike the other two above this is a batch feed type garbage disposal.
